Mechanical behavior of blood vessels: elastic and viscoelastic contributions
(2021-08-26)
Article
Open AccessThe mechanical properties of the cerebral bridging veins (CBVs) were studied using advanced microtensile equipment. Detailed high-quality curves were obtained at different strain rates, showing a clearly nonlinear stress–strain ... -
Modelo estocástico de hueso cortical de costilla humana para la predicción de fracturas mediante emisión acústica
(Universitat Politècnica de Catalunya, 2021-02-04)
Doctoral thesis
Open AccessIn this document, a non-linear constitutive model with micro-cracking and irreversibility is proposed for cortical bone of the human rib, extended with a stochastic fracture model, based on acoustic emission. Both models ... -
Prediction of mechanical properties of human rib cortical bone using fractal dimension
(Gordon and Breach Science Publishers, 2020-10-26)
Article
Open AccessA large number of post mortem human subjects was used to investigate the relation between the micro-structure of rib cortical bone and the mechanical properties using Fractal Dimension. Uniaxial tensile tests were performed ... -
Probabilistic assessment for clavicle fracture under compression loading: rate-dependent behavior
(2020-10)
Article
Open AccessPedestrians, motorcyclists, and occupants of vehicle involved in side impacts can suffer lateral impacts at the shoulder with sufficiently high forces to fracture the clavicle. While some previous studies have developed a ... -
Quantifying the effect of cerebral atrophy on head injury risk in elderly individuals: insights from computational biomechanics and experimental analysis of bridging veins
(2023-12-13)
Article
Open AccessThe objective of this study was to quantitatively investigate the relationship between cerebral atrophy and the risk of injury in elderly individuals. To achieve this, a sophisticated computational biomechanics approach ... -
Relation between mechanical and densimetric properties to fractal dimension in human rib cortical bone
(2023-07)
Article
Open AccessNumerous prior studies hypothesized a power-law relationship () between cortical bone Young's modulus (E) and density (¿) with an exponent , that has not been previously justified in the literature on a theoretical level. ... -

Revealing the role of material properties in impact-related injuries: Investigating the influence of brain and skull density variations on head injury severity
(Elsevier Ltd, 2024-04)
Article
Open AccessTraumatic brain injuries (TBI) resulting from head impacts are a major public health concern, which prompted our research to investigate the complex relationship between the material properties of brain tissue and the ... -
Viscoelastic characterization of a thermoplastic elastomer processed through material extrusion
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-07-18)
Article
Open AccessObjective. We aim to characterize the viscoelastic behavior of Polyether-Block-Amide (PEBA 90A), provide reference values for the parameters of a constitutive model for the simulation of mechanical behaviors, and paying ... -
Viscoelastic characterization of parasagittal bridging veins and implications for traumatic brain injury: a pilot study
(2021-10-18)
Article
Open AccessMany previous studies on the mechanical properties of Parasagittal Bridging Veins (PSBVs) found that strain rate had a significant effect on some mechanical properties, but did not extensively study the viscoelastic effects, ...
